/**
* To change a DisplayObject's tint/color, set this to the hex value of the tint you'd like
* to end up at (or begin at if you're using <code>TweenMax.from()</code>). An example hex value would be <code>0xFF0000</code>.<br /><br />
*
* To remove a tint completely, use the RemoveTintPlugin (after activating it, you can just set <code>removeTint:true</code>) <br /><br />
*
* <b>USAGE:</b><br /><br />
* <code>
* import com.greensock.TweenLite; <br />
* import com.greensock.plugins.TweenPlugin; <br />
* import com.greensock.plugins.TintPlugin; <br />
* TweenPlugin.activate([TintPlugin]); //activation is permanent in the SWF, so this line only needs to be run once.<br /><br />
*
* TweenLite.to(mc, 1, {tint:0xFF0000}); <br /><br />
